This article focuses on how to support SQLite (Web SQL) on the following platforms:
- Android
- iOS
- Windows Phone
Why should a SQLite Plugin used in Cordova?
- To follow the HTML5 Web SQL API as close as possible.
- To support Web SQL on Windows Phone.
- To deal with the same javascript functions on every platform.
- Fail-safe nested transactions with batch processing optimisations.
- Keeps sqlite database in a user data location that is known, can be reconfigured, and iOS will be backed up by iCloud.
- Works with SQLCipher for encryption.
Limitations of SQLite on Windows Phone
- Drop table is not working, seems like a bug in the .NET or C# SQLite library. To work around this, empty the table instead of dropping it.
- A high number of features in C# SQLite are disabled.
- Missing failure-safe transaction mechanism.
- Not (yet) working with SQLCipher for encryption.
What do I have to change in my existing applications?
Not much.Just replace "window.openDatabase" with "window.sqlitePlugin.openDatabase".
Don't forget to take a look at the limitations of Windows Phone Plugin.
How to install the SQLite Plugin
There are so many SQL Plugins available. I choose "lite4cordova", because it supports Cordova 3.x, it is easy to install and it is still in development.- https://github.com/lite4cordova/Cordova-SQLitePlugin

Windows Phone 8
If you are starting to develop for Windows Phone, have a look at this article first.To setup the project, type the following commands in the command line:
$ cordova create hello com.example.hello Hello $ cd hello $ cordova platform add wp8 $ cordova plugin add https://github.com/lite4cordova/Cordova-SQLitePlugin-WP-2013.12.git
Remove all files in "hello/www", except "config.xml".
Copy the testfile to "hello/www".
To build the project type the following commands in the command line:
$ cd hello $ cordova build
Finish! Open and run the project, execute the testfile to see if all works fine.
